Know Least Common Multiple of fractions 686/72, 520/66, 523/856 quickly i.e. 46641140 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 686/72, 520/66, 523/856 is 46641140.
LCM(686/72, 520/66, 523/856) = 46641140
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 686/72,520/66,523/856
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 686,520,523
Least Common Multiple of Numerators i.e. LCM of 686,520,523 is 93282280.
GCF of Denominators means GCF of 72,66,856 as per the given fractions.
GCF of 72,66,856 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 686,520,523
2 | 686, 520, 523 |
343, 260, 523 |
∴ So the LCM of the given numbers is 2 x 343 x 260 x 523 = 93282280
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 686,520,523 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(686,520,523) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(686,520,523) x common factors =1 x 2 = 2
LCM(686,520,523) = ( 686 × 520 × 523 ) / 2
LCM(686,520,523) = 186564560 / 2
LCM(686,520,523) = 93282280
Lets's calculate GCF of 72,66,856
2 | 72, 66, 856 |
36, 33, 428 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 93282280/2
Therefore the LCM of Fractions 686/72,520/66,523/856 is 46641140
